HEAD FR NSULATING-MACHINES.

Application filed May '22, 1912. Serial No. 699,05.

lie it known thatI L-CLAIR L. VAN Nass, a citizen olf tle United States, and residing at Akron. in the county of Summit and tilllate of Ohio, have inrented certain new sets of guidera` and dies. any or all or" which may he used at the saine time. and each oi which .sets adjustable independent` of the' other sets, whether adjustment ot the guider alone or die alone or adjustment oi both the guider and die is desired.

.i 'further object ot' my invention is to nroi'ide an insulatin.;T head which may los oi the single. or innlii )le forni.y and in which the ranistinuj'tion is such as to enable all the operating parts contained 'within the insulating; head to loe readily reached c outside of Vthe head.

still 'furtlier olojeetl of the invention is lo' provide in connection with-an insulating lie-.ith a relief ineansj preferably automatic in, its operation, 'whereby any excess pressure vthat may olitain within the shan'iher ot the insulating' head till loe ncliered.y so that the proper insulating of the wire .may not lie interfered With.

.l still further obje-.ct` of the invention is` to provide in' an insulating head. tampon attire regulating means so arranged to los in close 'proximity to Athe parts :if 'the head which il is desired to maintain at a proper temperature to prevent overheating,I- of the vinsulation material or chilling of the saine ironi the drawn therethrough, with the head disposed so that the dieslie horizontally or rertieally or at any angle between a horizontal and a .'ertical line.

A. still 1further and important object of my invention is to provide in an insulating head having a multiplicity of guiders and dies, means proriding Jfor the obtaining of a suiiicie't body oi.' material to coat the Wire within a space Where such material may be readihP fv'r-olled to prevent the same Yulcanin' ig or chliing.

With the above. general objects in View, and othrrs which Will appear hereinafter as the dei ned description proceeds, the in rention consists in the novel construction, combination, and arrangement of parts as will he hereinafter described and then claimed, and in describing the. invention in detail, reference 'Will be had to the aeconipanying drawings forming a part oi this specitication. i

My invention, in so far as the embodiments of the same are herein illustrated, relates particularly to that type of insulating heads known as side delivery, that is, the material with which the wire is coated is fed to the side of the wire, instead of in line with the wire, as in devices known generally in the art as straight delivery devices.

I have shown in Figs. 1 and 2, an insulating head illust-rating one embodiment of my invention, as attached to a suitable compressor having a feed or pressure screw for feeding the material into the insulating head. This compressor is designated genorally by the numeral 15, and since the insulating head in accordance with my invention may be attached to any suitable feed-- ing machine, no detailed description or illus tration of the latter is deemed necessary.

The insulating head is provided with a tace plate 16, adapted to he suitably secured to the discharge spoilt of the feeding machine or compressor in any suitable manner,

- and in the multiple form` of the insulating head shown in Figs. 1, 2, and of the draw` ings.`said plate is provided with an oblong i'eed opening 17 leading in to the cylindrical material receiving chamber 1S in the insulating head, such opening 17 at its inlet end, however` being flared outwardly into a circular receiving 'mouth 19, in order to better provide tor the reception of the insulatingr or plastic material from the coi'npressor. In the multiple form of head as shown in Figs. l to 27, the opening 17 is of elongated form in order to provide for the necessary admittance oi? sufficient material within the rela tively narron7 compartment or chamber '18, thus providing for the obtaining of a sutlicient body of material Within such chamber 1,8` but where the head is constructed with but a single dic and guider as in Fig. 7. obviously, the inlet passage or opening 1i may be circular in form, as such form of opening will 'teed sufficient material into the chamber 1S in a constrliction of insulating head such as shown in Fig. 'i'. The i nsulating head comprises, in addition to the face lplate. 1G a body comprising a main or barrel member 20 and a face or cap plate member 2l. which is fitted to and suitably secured to the body or barrel member 20 in any desirable manner. The chamber 18 or 18 above referred to is in the 4body or barrel mem ber 20. i

lhe member 20 has a continuous circular passageway 22, for the circulation of any suitable temperature controlling' liquid, such as steam, hot Water, etc., such passage surrounding the guiders to be herein after referred to, and being located in close proximity to such-guiders. Said member 20 has the circular continuous passa Way 23 which surrounds that guider an die disposed axially of the head, the passage-way being in communication with the passageway 22'throngh radial ways 24 as illustrated in Fig. 2 of the drawings. An inlet pipe 25 for the cooling or heating medium 1s connected with passage-way 22, and an outlet pipe 264 leads from passageway 23. Similarly, the member 21 is provided with a circular continuous passage-Way 27, and a cir cular passage-Way 28, an inlet pipe 29 being connected to passageway 27, and an outlet pipe 30 leading from passage-way 28, said two passage-ways being in commi'inication one with the other by radial passageovays in the saine manner as the passage-ways 22 and 23 are connected. I desire to call particular attention in this connection to the arrangementand location of these passageways, the same' being such that they are in proximity to the respective guiders and dies, so as to maintain the desired temperature around the guiders and dies, to keep the plastic material within the chamber 18 at the desired consistency.

ln the multiple die construction illustrated in Fig'. 1, the insulating head is shown with one ot' the guider and one of the die openings blanked, that is, the guider and die removed from the head, and the respective openings therefor blanlicd, by plugs Si 'lhe openings provided in the insulatingl nead for the guider-s and for the dies are uniform. so that any one or more ot such openingsl may be blan'ked at any time desired` the guider and the die being removed, and the plugs as 3l inserted in the openings.

The said openings designated 32 are threaded only apartial distance of their length, such threaded portions designated 21 being provided simply that they plugs may he secured in the openings to blank the saine when desired, the remainder o't the openingsl being Unthreaded so aa to provide a neat seat for the tie- Ineinber which connects the, guider and the die together.

The guider and the die, in the eonstriuI` tion shown in F 1 to 3 are both mounted in a tie member cmnprising sleeve portions 34 and 35, connected together by spaced bars 36, preferably having their inner edges rounded oil' as Clearly shown in Fig. of the drawings, so as not to interfere with the passage of the plastic material onto the wire. These bars lic within the chamber 18, While the sleeve portions ot the tie or connector are seated respectively in the o en ings 32 provided therefor in the mem ers 20 and 21. The sleeve port-ion 3-'t has a head 36 on its outer end which abuts against the out-er face of the body or barrel 20, While the sleeve portion 35 is interiorly threaded 'to 'receive the exteriorly threaded shank of tlf) llt)

one lock 'member does for all. The' outer @rid of the main or inner member ot the die is provided with a groove or nofrhes so tht it can r'edily be screwed into position loradjustd bye suitable tool.

The guider 39 is 'exteriorly threaded, und provided on ts'ontei' end with a hemd di such guider threading into the sleeve of the tie oi' eorineetor and having un nper ture 41 in its inner end substnntinllj.' on-- foriiiiii'gi: to the diur'nete'r oi the wire Vhenne e ted. The guider is secured in its ody ifiisted position by means oit' e loch: nut 42 r'nhted on the threaded shank of suffi guider, and iifhieh nbuts when the guider is iii 'd'jiisleid position against the outer lince of tliehead 'of the tie Connector. The sleeve end of the tie or connector ie ex teriorly threaded nt its outer end., to receive n lockiv nut' 43, which when screwed up 'gijain'st the outer fare of cap or end pl e 2l holds the tie 'or connector firmly in ite seis in the hend. The ohjeei. ot th struction of tie ineinher ivithdie und guider sleeves in one piece is to obtain zdiwhnelv perfekt tli'neine'nl of the 'die und guider. zu;
